Solar Panel Test Chamber testing solar panels, grid-tied photovoltaic inverters, or photovoltaic cells and modules.
Solar Panel Test Chambers are designed to test Solar Panels as per IEC test standards in order to prove their performance, reliability, durability and service life. There are three test methods that are performed; Thermal Cycle Test, Humidity Freeze Test and Damp Heat Test. Details of these tests are below:
Thermal Cycle Test: Thermal cycle test is performed according to IEC 61215:2005 standard to test ability of PV module to withstand effects of temperature stress. This test is performed between temperature 85°C and -40°C with fast changing rate. Number of cycles is run 50 or 200 times.
Humidity Freeze Test: Humidity freeze test is performed to determine ability of PV modules withstand against high temperature and humidity conditions followed by sub-zero temperature. In this this 10 cycles are run between 85°C with 85% relative humidity and negative temperature -40°C.
Damp Heat Test: Damp heat test is performed to test effects of long exposure of humidity penetration and high temperature. In this test is performed by applying 85°C ±2°C temperature with relative humidity of 85% for uninterrupted cycle of 1000 hours.
In order to perform above mentioned tests, we make Environmental Test Chambers or Climatic Test Chambers that can perform these tests effectively. As solar panels come in different sizes and dimensions; therefore, solar panel environmental chambers are also made according their sizes. Whatever the panel size, small, medium or large; we can design the test chamber that meets your requirement under your price budget. Our Solar panel environmental test chambers are made of imported components and fabricated with stainless steel sheets using CNC and laser machines. Digital touch control panel enables you to save temperature, humidity settings with controllable rate and dwell times. Data recording facility is inbuilt. Imported branded refrigeration system lets you experience trouble free negative temperature for long hours. Special stainless steel rack system is provided to hold PV modules inside chamber. We supply our solar panel test chambers all over worldwide at factory price with complete installation, commissioning and after sales service.

All operating procedures of the refrigeration system are completely controlled by the microcomputer controller.
There is a drip pan at the bottom of the compressor, which can collect the condensation water produced by frost.
The compressor has its own PTC temperature sensor, when the compressor is over-temperature, it can realize over-temperature protection.
The compressor has its own oil pressure protector to realize compressor oil pressure protection.
The high and low pressure protection device monitors the pressure of the refrigerant during the working process of the equipment. Once the pressure of the refrigerant is higher than the limit pressure of the system or lower than the minimum pressure set by the system, an alarm will be issued immediately and the power supply will be cut off until the fault is eliminated .
The refrigeration system all uses imported brand accessories, which are reliable in quality and ensure the stability of the system.
